Platine was soapy. I used to think of perfumes as either edible, soapy, or flowery when I was a kid. Not knowing how else to categorize them, I just had those 3 groups in my head. Then of course I had blends, such as the soapy floral... which was Platine.
Platine was meant to make women think of diamonds set in platinum bands or the glamour of platinum blonde hair.
